A totally weird experience!General

Well I encountered a really weird and not pleasent experience with my x10 today. I had it charging overnight like probably everyone who has one does and than I unplugged it to get started for the day. However, when I unplugged it from the usb cord, the screen got locked and flashed. So I turned it off and turned it back on. Well when it came back on, I had LOST everything that I had setup on my 3 screens! No icons, no nothing! Everything was gone except for the wallpaper or theme, which was the same I had setup. I did have ADW setup as my launcher, but all my launchers were gone as well. When I held down the center button, which would normally bring up my launcher option, it brought me to the homescreen.

So now I have to go through and resetup all of the icons and screens. Not a big ordeal, but what is troubling me is why did it even happen??
